Trait Implementations

impl LangHelper for JsonLdHelper

fn supports_prefix_diagnostics(&self) -> bool

Opt JSON-LD out of the generic prefix-diagnostics system.

@context has no syntactic distinction between a namespace prefix and a term alias, and terms can be declared via shared/remote contexts or used purely to define other terms — none of which the span-based, body-walking detector models correctly, so it produces false positives (see the module docs on swls_core::systems::prefix_diagnostic_helper). Undefined-prefix detection is moot too: JSON-LD silently drops terms with unknown prefixes, so they never reach a triple to flag.

fn prefix_name_at<'a>(&self, source: &'a str, offset: usize) -> Option<&'a str>

Extract the prefix name whose : was just typed inside a JSON string (e.g. typing : in "foaf:knows"), so on-type formatting can splice the prefix into @context. Unlike the text-RDF default, the term boundary is the opening double-quote of the string.

fn keyword(&self) -> &[&'static str]

fn default_position(&self) -> TripleTarget

fn unquote<'a>(&self, text: &'a str) -> &'a str

fn quote(&self, inp: &str) -> String

fn rename_placeholder<'a>(&self, raw: &'a str) -> &'a str

Given a raw token string from the document (e.g. <http://ex.org/foo> or ex:foo), return the bare text that should be pre-filled in the editor’s rename input box.

fn rename_wrap(&self, new_text: &str) -> String

Wrap the user-supplied rename text so that it is valid in the current language.

fn handles_prefix_completion(&self) -> bool

Return true if this language provides its own prefix completion and the generic [defined_prefix_completion] system should be skipped.

fn prefix_edits( &self, source: &str, rope: &LineIndex, name: &str, namespace: &str, _format: PrefixFormat, ) -> Option<Vec<TextEdit>>

Produce the text edit(s) that declare prefix name → namespace in this document, or None when it cannot / should not be inserted (e.g. the prefix is already present).

fn inlay_types_hint( &self, subject: &Range<usize>, rope: &LineIndex, last_type: Option<&Range<usize>>, types: Vec<Cow<'_, str>>, ) -> Option<InlayHint>

fn prefix_keyword(&self) -> &str

Return the source keyword used to introduce a prefix declaration (used only for display / span-finding purposes).

fn format_prefix_declaration( &self, name: &str, url: &str, format: PrefixFormat, ) -> String

Format a prefix declaration string to be inserted into a document.

fn model_based_rename(&self) -> bool

Return true if this language renames via the model-based systems in swls-lang-rdf-base (registered through setup_rename). When true, the core language-agnostic prepare_rename/rename systems skip this language’s documents to avoid producing duplicate edits.

fn blank_node_code_actions(&self) -> bool

Return true if this language supports the generic blank-node refactor code actions (extract a nested [ … ] to a labelled _:bN, and inline a labelled _:bN back into [ … ]).

fn supports_shape_validation(&self) -> bool
